In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the ...

This 2D example can be extended to a 3D situation, where waves are spherical and refocus exactly at the center of the sphere. However, in real life, one generally focuses light from one side, along ...

Each image was processed and projected, and the 0.5 μμm wavelength was selected to detect the wave packets. Images A, B, D, F, and G are at Ls≈150°; Image C at Ls≈285°; Image E at Ls≈245°. Image G is ...

With all the talk about the new wave pools that produce perfect waves all day long, all the new surf destinations around the world that are reported to be incredible and all the videos available ...
